truckee, around the math there, minus 18, beyond that just unbelievably told in the sierra. same thing around mammoth lakes. southlake, tahoe, 12 degrees below sooer row this morning. bay area, we can approach the same numbers again as we head into tomorrow morning. we had 20 nasdaq campbell. you can see lafayette and pleasanton in the mid 20s this morning. right now we have 30s and 40s outside. coldest spot, concord where the winds are light. very dry air out there helping our temperatures drop off. some spots in the north bay and the east bay hills, if you've got winds going tonight that's a little bit of good news. it will keep the temperatures up in the hills in the 40s. but wind protected valleys, 20s and 30s as you wake up tomorrow morning through 9:00. that's when the freeze warnings will expire. we're going to probably have more tuesday morning than just a slow warm-up as we go through the week. the reason why is this high. all that cold air which has been dipping down into california, more of it is going to move off to the east. warming mainly in the daytime hours.
